Alpha Magnetic Spectrometer (AMS-02) is a particle-physics detector from a module attached to the outside of the International Space Station (ISS). The temperature of the components in AMS-02 must be kept within their different operational ranges but also must be stable over both time and volume. Thermal modeling and simulations for the radiator and the electronic crates of AMS-02 were carried out by applying the Crank–Nicholson implicit solution. Based on reducing the temperature gradient of the radiator and the mass of the thermal control system, the layout of the heat pipes in the radiator was optimized to solve the overheating issue of the electronic crates. The non-operational and operational temperature dissipation for the thermal control system was calculated. The analysis results for the radiator and the electronic crates can meet the running requirements of AMS-02 on the ISS.

Alpha电磁谱仪电子包装箱的热分析和优化

Alpha电磁光谱仪（AMS-02）是一个粒子物理探测器，来自安装在国际空间站（ISS）外部的模块。AMS-02中组件的温度必须保持在不同的工作范围内，而且必须在时间和体积上均保持稳定。通过应用Crank-Nicholson隐式解，对AMS-02的散热器和电子板条箱进行了热建模和仿真。在降低散热器的温度梯度和减少热控制系统的质量的基础上，优化了散热器中的热管布局，以解决电子包装箱的过热问题。计算了热控制系统的非运行和运行温度耗散。
